Dehydrating mushrooms is a great way to preserve them and prevent spoilage. The process involves using a dehydrator or oven to remove moisture, extending the shelf life of mushrooms to a year or more. This method is especially useful for those who frequently buy fresh mushrooms, as it offers a cheaper and more versatile option with an enhanced flavour profile. Dehydrated mushrooms can be rehydrated and used in various dishes, shaved over pasta, or blitzed into a powder for an umami boost. The process is simple: clean and slice the mushrooms, arrange them on dehydrator trays, and dry at a specific temperature until crispy. Once cooled, the mushrooms are stored in airtight containers, ready for future use.

What You'll Learn
Choosing the right mushrooms
Firstly, always opt for fresh mushrooms. The fresher the mushrooms, the better they will store, and the longer their shelf life. Check for any signs of decomposition, such as slime, wrinkles, shrinkage, dark spots, or a bad odour. These are indicators that the mushrooms are not suitable for dehydration.
When selecting fresh mushrooms, a simple test is to break the stem from the cap. You should feel, or even hear, a crisp "snap." If the mushroom feels rubbery or bends instead of breaking, it's not fresh enough for dehydration. The exception to this test is shiitake mushrooms, which have tough stems.
Most edible mushroom varieties can be dehydrated, including Crimini or baby bella, shiitake, portobello, button, chanterelle, porcini, and oyster mushrooms.
It is best to avoid mushrooms that are on the verge of spoiling. Dehydration will not improve their condition, and they may not store well, leading to a shorter shelf life.
Finally, consider the thickness of your mushroom slices. Thicker slices will take longer to dehydrate, so plan accordingly. If you prefer larger mushroom pieces in your dishes, slice them thicker, but bear in mind the extended drying time.

Cleaning and slicing
To clean your mushrooms, use a damp kitchen or paper towel to gently wipe away any dirt or grit. Avoid washing the mushrooms with water, as this can cause them to darken during dehydration. Alternatively, you can dunk the mushrooms in a mixture of one part white vinegar and six parts water. If you are dealing with foraged mushrooms, they may only need a trim and a quick clean.
After cleaning, remove any tough and stalky stems with a paring knife or by tearing them by hand. You can save the stems to make vegetable stock.
Once cleaned and trimmed, you can leave small mushrooms whole or slice them thinly. It is best to cut the mushrooms into slices of uniform thickness, about 1/4 inch thick. A food processor fitted with a 2mm slicing disc can be used for slicing large batches of mushrooms quickly and efficiently.
If you choose to slice your mushrooms, arrange them on the dehydrator trays, ensuring that none of the pieces are overlapping or touching. This allows for optimal airflow, and the mushrooms will dry faster and more evenly.

Using a dehydrator
Drying mushrooms in a dehydrator is a great way to preserve them and extend their shelf life. This method locks in flavour and nutrients, and makes storage easier and more convenient. Here is a step-by-step guide to using a dehydrator to dry mushrooms:
Pre-drying
Before placing the mushrooms in the dehydrator, it is important to remove surface moisture. Lay the mushrooms on paper towels or a clean cloth and gently blot them. This step helps to reduce drying time and prevent mould growth.
Arranging in the dehydrator
Place the mushrooms on the dehydrator trays, ensuring they are spread out and not overlapping. This allows for even drying and optimal airflow. The thicker the slices, the longer they will take to dry, so consider this when slicing. Ideally, the mushrooms should be between 1/4 to 1/2 inch thick.
Setting the temperature
Set the dehydrator to a low temperature, ideally around 95°F-120°F. Do not exceed 50°C, as mushrooms tend to go black if dehydrated at too high a temperature.
Drying time
The drying process can take anywhere from 4 to 12 hours, depending on the size and moisture content of the mushrooms. They are adequately dried when they are crispy and snap easily.
Cooling and storage
Once dried, allow the mushrooms to cool at room temperature to prevent condensation during storage. Then, store the dried mushrooms in airtight containers, such as glass jars, and keep them in a cool, dark, and dry place. Properly dried and stored mushrooms can last for at least a year.

Oven drying
Oven-drying is a simple method to dehydrate mushrooms at home. It is important to clean the mushrooms thoroughly before drying them. This can be done by holding them under running cool water and gently scrubbing them with a brush. Once cleaned, the mushrooms need to be sliced into pieces of similar sizes. The ideal thickness is between 1/8 and 1/4 of an inch. Thicker slices will take longer to dry.
After slicing, gently squeeze the mushrooms with a clean dish towel to remove any surface moisture. Then, preheat your oven to a low temperature, ideally between 125°F and 170°F (52°C and 65°C). If your oven temperature goes below 140°F (60°C), it is recommended to prop open the door with a heat-proof utensil to lower the temperature and increase airflow.
Next, arrange the mushrooms on a baking sheet, ensuring none of the pieces overlap. Place the baking sheet in the oven and leave for one hour. Then, turn the mushroom slices over and return them to the oven for another hour. If the mushrooms are not completely dry, turn them over and place them back in the oven for 30-minute intervals until they are dry. The drying process can take anywhere from 4 to 12 hours, depending on the thickness of the mushrooms and the oven temperature.
Once the mushrooms are dry and crisp, remove them from the oven and let them cool completely. Then, transfer the mushrooms to covered glass jars for storage. Be sure to label the jars with the variety of mushroom and the date. Stored away from direct light and heat, the dried mushrooms can last for up to a year. To use, simply rehydrate by soaking in boiling water for 20 to 30 minutes.

Storing dehydrated mushrooms
Choosing the Right Container
Select an airtight container to store your dehydrated mushrooms. Glass canning jars with screw-on lids or resealable plastic bags are excellent options. If you opt for a glass jar, choose one with a tight-fitting lid to restrict airflow. For plastic bags, use thicker bags designed for extremely low temperatures, and squeeze out as much air as possible before sealing.
Preparing the Mushrooms
Allow the dehydrated mushrooms to cool completely before transferring them to your chosen container. If you're using a glass jar, fill it about two-thirds full. If you're using plastic bags, ensure they are compatible with low temperatures to avoid cracking or breaking.
Storage Conditions
Label your containers with the contents, including the type of mushroom and the date of drying. Store the containers in a cool, dry, and dark place, such as a cabinet or pantry. You can also store them in the refrigerator or freezer, especially if you live in a humid climate. Avoid placing weighty items on top of bags of dried mushrooms in the freezer to prevent crushing.
Maintaining Quality
Stir or shake the containers periodically to separate the pieces and ensure even drying. If you notice beads of moisture forming inside the container, return the mushrooms to the dehydrator for further drying.
Shelf Life
Properly stored dehydrated mushrooms can last for at least a year. However, always check for signs of spoilage, such as mould or off odours, and discard them if necessary.
By following these steps, you can effectively store your dehydrated mushrooms, preserving their flavour and texture for future use.

Frequently asked questions
Using a food dehydrator is the best way to dehydrate mushrooms. Dehydrators use a gentle heat source and constant airflow to gradually and evenly remove moisture.
Clean the mushrooms with a damp kitchen towel to remove any dirt or grit. Avoid washing with water as this can cause them to darken during dehydration. Remove any tough stems and slice the mushrooms into 1/4-inch thick pieces.
Dehydrate mushrooms at a low temperature (40-52°C) for 4-8 hours, or until they are crispy and brittle. The thicker the slices, the longer they will take to dry.
